I've created an LAS dataset and loaded a large amount of zLAS files (744) into it from another network drive. The store relatives path names box is unchecked. When viewing in the either a scene or a map, I cannot for the life of me get any points to display elevation. Only the red file extent boxes are appearing, and they are in the correct places at least. Any ideas what's going on here? This screen shot is whatn I'm looking at.
